Telnet Tips
It is not the intention of this manual to detail all of the operations and functionality of
Telnet; however, some basic level of understanding is necessary for operating the
Annotator 300 via Telnet.
Connecting to the Annotator 300 (Open command)
You connect to the Annotator 300 using the Open command. Once your computer is
connected to the unit you can enter the SIS commands the same as you would if you
were using the RS-232 link.
Connect to the device as follows:
1. At the Telnet prompt, enter open IP address.
If the processor is not password protected, no further prompts are displayed until you
disconnect from the Annotator 300.
If the processor is password protected, Telnet displays the password prompt.
2. If necessary, enter the password at the password prompt.
Connection to the processor via the Ethernet can be password protected. There are
two levels of password protection: administrator and user.
• A person logged on as an administrator has full access to all the processing
capabilities and editing functions.
• Users can select test patterns, mute or unmute the output, select a blue
screen, and view all settings with the exception of passwords.
By default, the processor is delivered with both passwords set to carriage return.
Once you are logged in, the processor returns either Login Administrator or
Login User. No further prompts are displayed until you disconnect the from the
Annotator 300.
Escape character and Esc key
When Telnet is first started, the utility advises that the Escape character is <Ctrl> +<]>.
Many SIS commands include the keyboard <Esc> key. Consequently, some confusion
may exist between the escape character and the <Esc> key.
The Telnet escape character is a key combination: the <Ctrl> key and the <]> key
pressed simultaneously. Pressing these keys displays the Telnet prompt while leaving the
connection to the Annotator 300 intact.
The Escape key is the <Esc> key on the computer keyboard.
